lie it known that l, @Hannes F. Massey, a citizen ot' the United States.and resident ot Chicago, in the county of Cook and State ot' lllinois,vhave invented certain new and uset'ul Improvements in Lamp Si'ipportinglStructures, ot' which the following is a Speci- 'tication My inventionrelates to lamp supporting structures, particularly to that classadapted .for use tor street lighting purposes. Among the importantobjects: are to provide a structure of which the parts can be readilyformed up of concrete or other eei'nent' material; to provide aconstruction and arrangei'nent in which lamp supporting brackets aredetacl'iable in order that shipment can belmade with greater safety andin more conopact form; to provide improved means for prixi'iarilySupporting brackets in placewbile grtniting is applied to till inthespaces between the' inner ends of the brackets in order to form acompact, solid and rigid structure; to provide conduit pipein eachiracket which will act .also as reinforcingl for such bracket and whichhas an upturned innerend to form a hook for receiving the means forprimarily holding the bracket arms in propeigposition while the groutingis applied; to provide the conduit. pipe in each brackets with upper andlower outlets at the end ol the. bracket. so that lamp structures may beapplied either to the topsoi the brackets to be held in up-righlposition, or to be `applied to the lower sides el the brackets to hangtherefrom; lo provide a conduit pipe at the interior ol the post whoseupper end extends between the inner end ot the brackets to torni anabutment therefor; to provide a compartment at thc-upper endet-the posthead into which the post conduit and the bracket.conduits extend and inwhich compartment'. connections may be made between main supplyconductors 1n the ypost. conduit and lead conductorsrunning through thebracket coi..r

duits` to the lampstructures; to provide a .cap for the post headconstruct-ed of eoncrete and having a duct for supportinor a top lampstructure and which communicates with said compartment, and in generalto provide improved, simplified andmore de sirable construction andarrangement in a lamp supporting structure of the class reterred to.y f

ln the accon'ipan \,'ing drawings Showing the various features oftheinvention: Figure l. is' an elevatioiml view with one ot' the lampstiaicture."y removed and the end of one bracket in section; Fig. 2 is aplan View with thc eap removed; Fig. 3 is an enlarged sectional view ofthe post head taken on plane f-hf, Fig. Q, showing the inner ends of thebrackets supported therein just before application of the groutingmaterial; Fig. 4 is a sectional view taken on plane fil-4, Fig. El. andFig, 5 is a sectional view taken on plane 5&5. Fig. l.

Reterring to the drawings a post 5 is built up integral ot' concretewhich may be properly reinforced in any suitable manner. 'lhe head (i ispolygonal and has` lateral passageways 7 each extending from the centerto one olj its faces t'or receiving the lamp supporting` bracketstructures 8. These passageways are formed by inserting a Core in themold, and when the core is removed only the corner posts t) will remainbetween the base t3 and top 6" ot the head, the lateral channels 7 beingbetween these posts. As shown in the drawings, the head rectangular andhas lour lateral passageways for receiving and spacing four bracketsninety degrees apart. The top Gl of the head is hollow lo t'orm acompartment l0 for containing the. electrical joints as will bedescribedlaterA The peat 5 has running centrally therethrough a pipe ll whichextends centrally through the head between the corner posts andterminates in eon'lpartinent 10 for lead ing current supply conductors'l2 to said eonnnzrtn'ient from the base ot the post where suchconductors` connect with mains in the street.

Each lamp supportingbracket S is tin-ined integrally ot concrete orother ccn'ientitious material and comprises a body part Sf-Lwhich itssnugly into one oll the passagewayh T of the head between the, adjacentcorner posts. ltlxtending laterally from the upper end ot' :he body partis anl arm SL' and extending diagonally upwardlj.' trom the lower end olthe body part is' the brace 8, the end` 8 being of rectangular crosssection as shown. Extending longitudinally through the arin Sb is thepipe l?) whose inner end 11:5 is deflected upwardly and ,spaced a.distance from the body to leave a groove ll. The outer end of this pipeterminates in a Tfpipe fitting 13b Whose upper end is lushwith the topsurface ot the arm and whose lower end receives an extension 13C whichprojects bcyond the lower tace 8 of the bracket for receiving lampsupporting mechanism. The inner end 8 ot the body 8 of the bracket istapered and of conical form, this end beine` below the pipe end 13a.Each bracket structure is reinforced in any well known manner and thepiping running therethrough also serves to strengthen the structure.When the brackets are to be applied to the post the bodies thereof areinserted in the various channels 7 which they snugly tit and with theends S abutting against thc pipe ll. extending through the head o't thepost. ring 15 is then dropped into the groove llbetween the pipe ends 13and the body parts and the brackets are thus held in proper position.Such ring may be in the nature of several turns ot' wire looped aboutthe pipe ends lil". frt'ter the brackets are thusl locked in placegrouting material lt' is poured into the pockets 17 between the tapered'laces ot the ends Se and the entire head structure thus becomes solidup to the tops ot the brackets. \Vhen the brackets are thus secured thepipe ends 13 all open into the compartment l0 and this compartment willaccommodate the joints between the main supply conductors 1Q and the.leads lb running through the pipes 123 to the lamp structures. The upperend of the post and the compartment 10 are preferably covered in orderto protect the conductors` and joints and I therefore provide aremovable ea p it) of concrete, and this cap mayserve also to supportthe lamp structure l which is supported from the end of a pipe l0extending centrally through the cap and leading to compartment l0 sothat connection can be made between the l"ads to the lamp and the mainsupply conductors.

s the pipes lil have outlet to both the tops and bottoms ol thestructure ends, the lamp structures l may be supported in uprightposition on the tops ot' the brackets or to hang l'rom thex bracket endsas shown in the drawings. When the lamps are hung as shown, plugs ll arescrewed into the upper ends et' the T-tittings lll" to protect the leadswithinthe piping. When the lamps are hung as shown. the threaded outerends of the extensions lll" receive holders /L for globes g. Theseextensions are usually of larger sized pipe and reducer tittings 7- aretherefore applied thereto on which lamp sockets s may be secured torreceiving the lamps When the lamps on tho brackets are to be supportedin upright position the plugs 2t are rcmovtd and suitable pipe lit'-tings inserted in the Tdittings to support the lamp strmttures, and theextensions 13 are then preferably capped to protect the conductorswithin the piping lit.

The post may also be adapted tor accommodating illuminated sign plates.One arrangement is clearly shown in Fig. 5. The compartment Q2 is formedin the post and extends across one corner thereof in order to have theside outlets and 2l which are covered with glass or other plates and loon which the street name is painted or otherwise provided. The cornersection 27 will secure one'or more lamps 28 and on the rear wall Q9 ofthe compartment a reflector IKO is provided for reflecting the lightfrom the lamps through the letter plates.

I thus provide a lamp supporting struc ture in which the Various partscan be readily built up of concrete or other cen'ientitious material.The bracketsl being llat can be compactly packed for shipping purposesand a'titer the post part is installed inthe ground, these brackets canbe quickly inserted in the head channels and the ring slipped over thepipe ends 13 and the grouting material poured in so that the bracketsare then securely held:in/proper position and alinement. Connectiionsare then made between the main supp'y conductors and the lamp .structureleads and the cap then applied. The brackets c'an of course be appliedbefore thc post is set into the ground-it desired. lt one ot theIbrackets should at any time be broken it can be readily removed bywithdrawing thel ring 153 and replaced b v another bracket. 'l'he entirestructure has a very neat and pleasing appearance.

t do not desire to be limited to the precise construction and arangementshown and described as changes and nuulitications are no doubt possiblewhich would Istill come within the scope of the invention as set up inthe following claims:
